The Legend of Zelda: Majora's Mask 3D Wiki Guide

Gimme a Break

Look for the pot-breaking mini-game along the Great Bay coast. Don the Zora mask and use your "boomerangs" to take out all the pots. Adjust your position by moving closer and farther away to get them all. The reward for completing the challenge is 90 Rupees.

If you don't want to waste any time at all, just get one of the Exploding barrels from the Goron in the Goron village. Place the barrel in the middle of the pots and then put on the Zora mask. All the pots will get blown up and you'll still get rewarded.
